• 2．Acid rain（酸雨） is very harmful to the environment because it makes living things die.Acid rain affects life in the water as well as life on the land.Il is even worse in the water because the fish need the water to breathe.When the water gets polluted，the fish get sick and end up dying.
     All rainwater contains some level acidity（酸性）.Acidity is measured by PH，which stands for potential of hydrogen（氫）.The PH scale measures the amount of acid in a substance.PH is measured on a scale from 0 to 14，with 7 being neutral（中性的）.The lower the number is on the PH scale，the more acidic that substance is.Normal rainwater has a PH of 5.6.When the PH level of rainwater goes below 5.6，it is considered acid rain.
     All of the sea life will die when the water becomes too acidic.For example，all fish will die when the water goes below a PH of 4.5.Most of the frogs and insects that live around the water will also die when the water reaches a PH of 4.5.When the water has a PH of 5.5，all of the bottom-dwelling bacterial decomposers（分解體），animaLs that eat the remains of the food that other animals don't want，will begin to die.When these decomposers die，they will leave the under-composed food on the bottom.This will make the water dirty and polluted.All fresh water shrimp will die when the water has a PH of 6.0.Aquatic plants will grow the best when the water has a PH between 7.0 and 9.2.If the acid rain problem gets worse，all of the sea life will eventually be gone.
  
  （1）Acid rain

  .
  A．does more harm to life in the water than on land
  B．will kill the living things as soon as it touches them
  C．is rainwater which contains any amount of acidity
  D．is a substance which has potential of hydrogen
  （2）Which of the following can die most easily in acidic water？

  .
  A．All fish.
  B．Frogs and insects.
  C．Bacterial decomposers.
  D．Fresh water shrimp.
  （3）According to the passage，we know that

  .
  A．if the PH of rainwater is 5.6，all of the sea life will be gone
  B．if the PH of sea water is below 7.0，it is not a problem
  C．if the PH of rainwater is below 5.6，it is dangerous.
  D．if the PH of sea water is below 4.5.jye.ai of the sea fish can't die
  （4）This passage mainly tells us

  .
  A．the definition of acid rain
  B．how to measure rainwater's PH level
  C．the effects that acid rain has on sea life

• 3．Isle Royale is surrounded by the deep blue waters of Lake Superior，the largest freshwater lake on Earth.The only way to get there is by boat or seaplane.The National Park Service operates shuttle boats that take visitors to Isle Royale.The boats leave from two Michigan ports.A boat trip to Isle Royale takes three to five hours.Waters are often extremely rough.
     Modern copper mining began in the late 1800s.resulting in large areas of the island being burned.This led to settlement development.Soon，Isle Royale became popular for summer homes.It became a national park on April 3，1940.In 1980，officials named it an International Biosphere Reserve（生物圈保護(hù)區(qū)） because of its unique ecosystem.
     Isle Royale offers hiking，camping，boating，and even scuba diving.The National Park Service protects 11 sunken（沉沒的） boats for divers to explore.They are reminders of Lake Superior s commercial shipping history.The sunken wooden ship called The America is one of the most popular dive sites.The America carried passengers，mail，and supplies to many towns along the shores of Lake Superior.It first launched in 1898，and was used until 1928，when it was damaged.It sank to the bottom of the lake soon after.
     Visitors to Isle Royale share the trails with a well-studied population of wolves.Scientists believe wolves walked there during a freeze of the lake sometime in the 1940s.Researchers closely record their population numbers.Much of the research takes place during the winter，when the trees are bare.The researchers fly over the island to observe the animals from above.
     Animal research is the only winter activity going on at Isle Royale.The national park is closed each year in late October because of the terrible weather conditions and reopens in spring time the next year.
  But for the other months of the year.Isle Royale offers green forests，and clear blue waters.Its excellent scenery and unusual location keep visitors returning year after year.

      Little Tom was a nine years old boy who always behaved ill.When he saw a person passing by in front of him，he would make fun of him and even throw stones at him.He thought it was fun.
      One afternoon，when little Tom was on the way home after school，a stranger passed through the village.His dress was plain and somewhat old，but neat and clean.He carried a luggage in his hand，and he wore a black hat.As soon as he saw the stranger，Tom whispered to his playmates， "Now for some fun!" He then silently went toward the stranger from behind，knocked off his hat and ran away.The man turned and saw him，but Tom was out of hearing before he could speak.The stranger put on his hat，and went on his way.Again did Tom approach，but this time，the man caught him by the arm.However，he just looked at the boy for a moment in the face，and then pushed him from him.No sooner did the naughty boy find himself free again than he began to pelt the stranger with dirt and stones.Accidentally，a stone hit the man on the head and he was badly hurt.All the boys now ran away，and Tom ran across the fields to his home，feeling frightened.
       Before he entered his house，his sister Rose came out to meet him，with a beautiful toy and some new books in her hands.She told Tom excitedly that their uncle，who had been away for several years，had come home，and was now in the house；that he had brought beautiful presents for the whole family；and walked on foot，so as to surprise his brother，their father.
